Enable Office 2007 Add-Ins for All Users

Hi folks!

I work in a school environment with approximately 120 Windows XP Service Pack 3 workstations running Office Enterprise 2007. There is a particular add-in -- in this case, the Solver add-in for Excel -- that I would like to have enabled for all users on all workstations. However, the standard behavior of Office 2007 is that add-ins are installed on a per-user basis.

Is there any good way for me to enable this particular add-in for all users without each user having to enable it individually?

There is a solution provided on the HP forums which worked for the users. Can you try this and see if this works out for you?

"The following solution worked for me to deploy Excel add-in using administrative install for each user without giving them local admin rights:

1) Deploy-installed to all PCs *just once* using an account with local admin rights. Got it to install the add-in at the default location "C:\Program Files\TRIM Context\" instead of installing it every time whenever each user logs on.

2) Now this is the kicker: Add 3 registry keys (pertaining to the add-in in HKCU because the add-in is activated "per-user") to the domain user profile on logon. This ensures the add-in is activated each time the user logs on."

If macros are enabled, then take a  look into putting this code...

AddIns("analysis toolpak").Installed = True
AddIns("solver add-in").Installed = True

in an event that is common to all users (Workbook_Open event of a standard worksheet template, Personal.xlsm for each user, etc.)

Unfortunately, due to security concerns in this environment, macros are disabled.

I believe I understand. However, how do you get the add-in to install in a specific folder, as the instructions say? There doesn't seem to be that option.

I have Solver Add-In installed on my PC and here are the registry settings

Within "HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Excel\Options", look at the OPENx subkeys -

I have the following -
OPEN1 = "C:\Program Files (x86)\Microsoft Office\Office14\Library\SOLVER\SOLVER.XLAM"

(Note: The number will differ based on your Office Version, I have Excel 2010 so it is 14.0)

Excellent! This method worked perfectly!

For the reference of anyone else who may come along and check out this solution, the registry key for Office 2007 is within HKCU\Software\Microsoft\Office\12.0\Excel\Options.

Thanks for the help!
